Arc St Pro Snowboard Bindings - Black 2026
The lightest, and highest performing splitboard bindings in the world.
Made with extreme attention to detail, premium materials, and custom components. Our PRO Series bindings are the culmination of our years in the forefront of splitboard binding technology and manufacturing. We built these for splitboarders who want the best of the best.
Spark Arc bindings have been improved in just about every way over the summer, and the Spark R&D Arc ST Pro Splitboard Bindings go even further in their quest for the lightest and most efficient splitboard connection possible. Spark started by initiating their "ST" (Smooth Touring) program on just about any connection with inherent friction, and using a fresh overmolding process proceeded to drastically improve both performance and durability. With the Pro Series bindings, they jumped at any opportunity to cut weight without sacrificing performance, adding carbon to the highbacks, hollowing out the pivot pins, and substituting alloy hardwear for stainless steel where possible. The Arc ST Pro is the softer flexing of the company's offerings, best for those who prefer a surfier, more forgiving ride.
Gram Counting
A 65% weight savings is found by replacing 7 stainless steel components with 7075 aluminum hardware, custom made in-house. Not only is the pro hardware lightweight, it also adds splitboard specific features. We switched from phillips to hex heads where we could, making screws less likely to strip. We also crafted our aluminum heel loop screw with a custom screw head shape that has more than double the drive depth of a standard button head screw to avoid stripping. Additionally, an unthreaded shoulder improves the connection with the heel loop.
